Application filed .Tune 6, 1910. Serial No. 565,319.

To all whom it may concern:

Be it known that I, EDWARD L. ADREON, Jr.,'acitizen of the UnitedStates, and resident of St. Louis, Missouri, have invented certain newand useful Improvements in Tie-Plates, of which the following is aspecification containinga full, clear, and exact description, referencebeinghad to the accompanying drawings, forming a part hereof. o

My invention relates to tie plates, and the object of my invention is toconstruct a tie plate having a rigid bearing for the spike.

A further object of my invention is to construct my tie plate by rollingor pressing a number of the same from a single piece of material andthen shearing the plates from said piece of material in the widthsdesired without waste.

For the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts which will be hereinafter morefully set forth, pointed out in the claims and illustrated in the socompanying drawings, in which:

Figure l is a top plan View of a number of the plates formed from asingle piece of material; Fig. 2 is a top plan view of one of the platesprepared ready for use; Fig. 3 is a section taken on the line 33 of Fig.2; Fig. 4 is a View, partly in section, illus- .t'rating a center punchmark for a spike opening through one of the projections; and Fig. 5 is afragmental plan View showing an ordinary spike head in place.

In carrying out my invent-ion I take a single piece of material and rollor stamp it by any suitable rolling or stamping means and in the desiredlength. By rolling or stamping, I form on the railbearing surface of theplate a shoulder for the edge of the base of the rail, and integral withsaid shoulder a series of projections arising from the top surface'of'the plate, which projections, as illustrated in Figs. 1, 2 and 3,are formed integral-with the shoulders of the rail bearing surface ofthe plate. The projections on one side of the plate are staggered orofi-set in relation to the projections formed on the opposite side ofthe plate. By doing this, the plate is more readily and perfectlyrolled, because at all times during the operation of rolling there issubstantially an equal amount of material beneath the roll. .However,this staggered or ofi-set relation of the projections would not be ofany advantage if the plate was stamped or cast. However, it is hi hlyadvantageous if the plate is rolled. After the plate has been rolled,tie plates may be sheared therefrom in any widths desired without waste.In Fig. l I have shown in dotted lines the points where a plate may besheared.

Having described in a general way the method, I will now proceed todescribe the construction of the individual tie plates, reference beinghad to Fig. 2 as the preferred form.

1 indicates the rail bearing surface of the tie plate, and formedthereon are oppositely disposed shoulders 2 and 3 for the alinement ofthe base of the rail. Formed integral with the shoulder 2 is a series ofprojections l, 5, 6, 7 and 8, and formed integral with the shoulder 3 isa series of projections 9, 10, 11 and 12. These shoulders are, asheretofore stated, struck up or formed on the top surface of the plateby rolling or stamping, and likewise, the series of pro-- jections areformed. These projections constitute one of the parts of my invention,for the reason that when. a spike opening is formed through the platethrough this projection a rigid bearing is formed for the spike.

In Fig. 2 I have illustrated spike openings formed through the plate andthrough some of these projections. Such openings are intended for screwspikes, and any number of openings can be formed in each plate, as

desired. These openings are formed by being punched or drilled throughthe plate and the projections. They also may occupy any positionrelative to the shoulders.

In Fig. 2 I have illustrated the openings as set back from the shoulder3, and also the openings as projecting slightly beyond the shoulder 2.When they are completely set back from the shoulder, as illustrated inthe left hand side of Fig. 2, all wear is received by the shoulder 3,and when the openings project beyond the shoulder 2, as illustrated inthe righthand side of Fig. 2, the spikes receive part of the wear andact to wedge the base of the rail against the shoulder 3. In practice,it is more practical to force the base of a rail against the outsideshoulder of the tie plate. By this arrange ment of spike openings afurther advantage follows after installation, especially where the plateis applied to the rail at curves in which instance the plate may bereversed, placing the shoulder 3 against the outside edge of the rail,which narrows the gage and compensates for the wear of the rail by usingthe same holes and fastenings, and saves the necesslty of plugging thet1e and forming new holes.

In Fig. 3 it will be noticed that the top surface of each projectioninclines slightly downward toward the rail bearing surface for thepurpose of affording the proper of material, havin a shoulder and apro-' jection, and a spike opening formed through said projection, theouter walls of said projection converging and meeting each other at anangle, and projecting rearwardly beyond the opening so that when a spikeis driven through the opening in said projection the head of the spikewill extend over at least a portion of the outer Walls of saidprojection, for the purposes stated.

2. A tie plate pressed from a single piece of material and provided onits top surface on each end with a shoulder and spike bracingprojections formed integral with said shoulder, there being spikeopenings formed through said plate on one end, away from therail-bearing line of the shoulder, and on the opposite end projectinginwardly beyond the railbearing line.

3. A tie plate pressed from a single piece of material having arail-bearing shoulder arising from one end of said plate and arailbearing projection arising from the opposite end of sa dplate,'there being sp ke openings formed through said plate outwardlyfrom the railbearing line of the first men tioned shoulder, andspikeopenings formed through the other end of said plate inwardly of thebase of the rail. r

4. A tie plate pressed from single piece of material and provided with aseries of projections at each end, said projections being staggeredrelative to each other, and a shoulder formed integral with each row ofprojections, said plate being provided with a number of spike openingsdisposed in different positions laterally relative to the'railbearingline in order to accommodate rail bases of different widths.

5. A tie plate provided on its top surface withtwooppositelyformedshoulders, a series of projections formed integral with saidshoulders, there being spike openings formed throughsaid plate operatingfrom the railbearing line of-one of said shoulders, and spike openingsformed through said plate inwardly beyond the rail-bearing line of oneof said shoulders, whereby said plate maybe reversed and reapplied tothe tie by using the original openings and fastenings.

6. A tie plate having formed thereon a series of projections, the innerwalls of which form two rail-bearing lines, there being spike openingsformed through some of said projections away from the inner wallsthereof, and spike openings formed through said plate extendingpartiallybeyond the inner walls of some of said projections.
